Application To all 107mm it ma -3; concern:

Be it known that 1, 5 onN W. Srnrnnnson, of Toledo, in the county of Lucas, State of Olii ,.li21-VO invented a. new and useful Axle- Bez ring Device for Cars, of which tho following is it speoilieetion, reference being llltl to the fi-C-COI" ninying drawings, forming part oi this s ooiiieetion, in which l igure l is {L cross-section oi a j ournnl box secured in place in n truel side trains, and illustrating tho bearing device; Fig. 2 is it phtn Vic-W oi" the parts slmwn in Fig. l Fig. 3 is A longitudinal section through the jourinil box uru lli'nine, on tho linollllll ol' l ig. 1; Fig. 1} is it View similar to Fig. 1, but showing tho journal box out of slineinent with tho *ertiosl Walls of the true]; siile frzuno; Fig. 2L seotionzil detail of the compensator blooh: Lilli 6 is at bottom )llLll view of the JZLITUJ.

The purpose oi my invontion is to provirl means for placing 01" journal boxes in th side l'ren 2s of railway ours. lfhore the sill frzuno nnule of a single costing having an opening for tho IQL .ption of a journal box it often happens that the space in the side frame which receives the journal box is Wnrpeil mill untrue, zunl the journal box eithor of such cases the list top of the journal box and Lho'lhit umlor side of the side irsnio coming together will tilt the journ: box out of its proper v'c-rtirzil position so t it ezrnnot be properly hehl. This iliilE-cult s st-s in built-up truol; frames. This is :1 serious iliiliculty, but it is oorroeteil by my lDVGIllJlOE'L lln tho accompanying drawings, 4 is the trueli side frame which I show east in a. sin gle piece, having at the ends openings 5 to recoivo the journal box 3.

6 the our axle journal, 7 is the journal blz). s, Bis the Wedge, and 8, 8 are the bolts which ass through the top and bottom members of the side frame for the purpose of holding the journal box in place. These .bolts may be secured. by nuts 9 u nil the holes in the side frame which receive the bolts may be drilled. alter the side frame has '1- J.- T W r L i A. Specmostion oi Mott is rates-t.

S erizi'l been east, 01

l the casting ior tlile side frame.

111 musing To piovii box or in the siile frame, and to enable the journal be always to assume a vertical position mrallel with the bolts 8, 8, I provide a compensator which 1 show in the form of east block or plate of metal 10 having lateral lh-tngg es it) by which it is confined in position against the top ineniber oi the side frame. The lower face of this compensator lies :1 socket 10 of spherical form which is adapted toniz'rtoh with {L ball-shaped projoetion 3 on the top of the journal box so that it the box openinq in the side frame should beirregulsr, or of the top of the ournzi-l hox should boirregulmythe journal box will adjust itself on the rocking bearing provided h this ball and socket formation, and although the top of'the journal box rney not bo parallel with the unrler side of the top 'nnbor oi the side frame, the journal box will be pcrpsinlioulsr and will be parallel with t confining bolts 8. The journal. be); v. thus be i'lfilll in. the side frame withn, and will be properly ositioned. is illustrate in Fig. i in Whicn I show it ruins of Very irregular form, the bolts perpendicular but out of parallel iii-s members of the truck sideznnl the top of the ournal box being uinst the compensator l0 and being hereby to be maintained by the bolts in perl'ert equilibrium.

The top of the journal box is preferably nroviilorl with vertica flanges which enibraco. the Sit es tho compensating piece. The device also preferably used with a bell and sot-hot eonneution between the We lge and the in! rior surface of the top of the journal lmx, although these parts-sire not essential to my invention as broadly claimed.

in Figs 7 and S I have shown in T inven tion as up ilieil-to :itruck sicl frame coin- PUSULl o'l' two members 11 and l2, between which tho box is seated and having an open sent for the journal box. Fig. 7 shows the application 'Wl'lQl'G the SlllO frame has been clistortotl in its irnnuiacturo, While 8 l tlr. app]. is without iilistortion. The construction and :irrungmnent of: the parts constituting the invention is substantially the some as in the lUilil first described, and corresponding 1 5i erenoe ehsrsoters are applied to the eorrele forinequnlities in the journal i Anon Where the side frame sending parts. The bolts 8 pass through t e side frame extension 11 and through the bottom member 12, which is shown as consisting of a wrought tie-bar.

In the modification shown in Fig. 9, the

compensator 10 is omitted and a ball and socket joint or hearing 13 is formed between the top of the box and the extension of the side frame, and theball and socket connection between the wedge 2, and the top of the journal box is omitted, the wedge having a flat bearing against the journal box.

Fi 10 shows another modification in whic 1 the side frame 14 is an integral piece without outside connection between its upper and lower extensions 14 and 14, thereby leaving an opening for the insertion and removal of the journal, box and axle without pulling the side frame from the truck. 15 are the bolts which secure the journal box 16. The bolt-holes atthe lower extension 14 are of angular, preferably.

hexagonal. form, and of larger diameter at their upper portions 17 than at their lower portions 18. The portion 19 of the bolts which fit in these holes are made of corresponding form. The middle portions 20 of these bolts which engage the sides of the journal box are round, but are of larger diameter than the end portions and are of eccentric or cam form. in assembling, the proper position of the axle in the truck is determined, and the journal -box is then placed in its true position. The bolts are then turned into proper position to hold this box in this position, and are held in their adjustment by the engagement of their hexagonal portions with the holes in the extension 143. In. this manner, the position of the journal box is determined, not by the bolt-holes in the side framebut by the adjusted position of the bolts. if the axle is out of' its true position, the bolts can be loosened, raised, and readju'sted so as to move the journal box nearer to or farther away from, the center of the truck. Fig. 10 also shows a hearing pin 2'1 of elliptical or lenticular cross-section, its upper convex surface filling a concave bearing in the coinensator 22 and its lower convex surface )earing in a concavity 23 on the top of the journal box. The construction shown in this figure is also applicable to non-integral side frames.

It will be understood by those skilled in the art, that various other changes and modifications may be made, and that the ball-an(lsockct hearing may be formed in various ways; also that the invention is applicable to side frames of various constructions as well as to the particular forms shown.

13. An arch-bar side frame for car trucks having an opening for a journal box of greater width than the box, a journal box having a rocking bearing in its seat to permit it to assume an initial vertical position in said'opening, and means for fixedly se curing the box in its adjusted position substantially as described.

14. An arch-bar side frame for car trucks having :an opening for a journal box of greater width than the box, a journal box having a rocking bearing in its seat to permit it to assume an initial vertical position in said opening, and bolts engaging the sides of the box and securing it in its adjusted osition, substantially as described.
